Nasolabial bilateral cyst as cause of the nasal obstruction: Case report and literature review

Abstract

Summary Introduction:?The nasolabial cyst is a rare disease, usually unilateral, benign, of embryonic origin, located in soft parts from the nasolabial folds and nasal wings. The diagnosis is essentially clinic, take into consideration the cyst topography, that is usually asymptomatic. Objective:?This article has as main goal the description of a unusual case of nasolabial bilateral cyst with nasal obstruction, its treatment, anatomic pathological and accompaniment, besides the literature review. Case Report:?Female patient, brown, 24 years old, showing bulging in nasolabial region and nasal obstruction. Physical and complementary exams with nasolabial cyst. Indicate surgical treatment of excision of the lesion. Final Considerations:?The nasolabial bilateral cyst, although is rare, is a possible cause for the nasal obstruction, with good response to surgical therapy.

Diagnosis of the nasolabial cyst: case report

“…However, its growth may determine compression of palatine structures, especially in the lateral inferior limits of the nasal fossae, allowing observation of deviation of the line demarcating the floor of the nasal fossa in the occlusal radiographic exam 6 . In addition to this, the pressure exerted by the nasolabial cyst may produce superficial erosion of the external surface of the maxilla 7,8 .…”

“…With regard to the form of treatment, the literature is unanimous in indicating complete surgical excision of the cyst 3,6,8,9 , with simple enucleation being preformed through intraoral access, with an incision in the gingival labial sulcus and rhombic dissection of the lesion. As the cyst walls are intimately related to the mucosa of the nasal vestibule floor, in the majority of cases, the surgical maneuver may result in laceration of this mucosa.…”
